Other Tips

✤ Spacing may vary, but easting and northing must be same length

✤ Reports will routinely omit the Grid Zone Designator in the body of text (may be included in header metadata)

✤ Not all grid zones or 100km squares are actually squares

✤ Typos in report may geocode some coordinates to Antarctica

✤ I am not a map nerd. Someone else can tell how to use in ArcGIS.
